•
An audible tone will beep 3 times whenever the component is out of the setting
tolerance. A single « beep » tone indicates the component is within the setting
tolerance.

Notes : The tolerance mode cannot be activated if the tested display is
either « OL » or «0000 » ; nor can it be activated if the tested
capacitance value is below 10 counts.
The tolerance mode is only available in manual ranging ;
however, activation while in autoranging will automatically set
the meter to manual ranging and cause calibration prompts to be
displayed in the recommended ranges.
The tolerance mode cannot be activated if the meter is set at
autoranging with Data Hold mode activated.
3.4.8. Auto / Manual range
Autoranging is default status when the meter is powered on. User can push the
« Range » key to select desired mode.
3.4.9. Fuse detection
When the CPU detects that the signal
source protective fuse 70 mA / 250 V is
open, the « Fuse » Character will appear
and an internal beep will sound
continuously. In this situation, none of
the function keys can be operated and
all other meter functions will be
discontinued. Fuse replacement is
required. figure 9
3.4.10. Parallel / Serie Mode
The IX 3131 is capable of displaying Parallel and Series mode data for all ranges.
The parallel mode is default for Capacitance and Resistance measurements and
the series mode is default for Inductance measurement.
However, each data can be transformed to the other mode reading in the following
step.
•
To get parallel mode data under the
Inductance measurement, press the DH key
and then press and hold D/Q button for one
second. When the "PAL" character appears
on the secondary display, the Parallel mode
data will display. Press D/Q button again to
exit.
